Measuring, reporting, and comparing identical outcomes across treatments and treatment centers will provide patients and providers with information to make informed treatment decisions. We defined a set of outcomes that we recommend being tracked for every man being treated for localized prostate cancer.

271 Background: The prospective collection of standardized, patient-centered outcomes for men with prostate cancer will allow intra- and inter-institutional comparisons, patient education, self-assessment and dissemination of best practices. We lack recommended standardized sets of such outcomes. Methods: Through the International Consortium for Health Outcomes Measurement, a working group of urologists, radiation oncologists, registry representatives and patient advocates convened to develop a recommended minimum set of measures which institutions would collect on all prostate patients. Using a modified Delphi method over a series of in-person meetings and conference calls, a final set of recommendations was developed. Results: Approximately 30 experts in prostate cancer care from North America, Europe, Australia, and the Middle East participated in the process, representing academic centers, registries and patients. We defined the scope of this initial effort as outcomes related to the management of localized prostate cancer. The group recommended cross-disciplinary measures applicable to a variety of treatment approaches from surveillance to radiation and prostatectomy. Standards were identified for disease control definitions as well as baseline patient and disease-specific risk stratification factors. Domains of patient reported outcomes to be tracked in follow up were identified including urinary incontinence, urinary irritation, bowel irritation, sexual function, and symptoms related to hormonal therapy. Finally, specific tools to assess these domains and gaps in our current tools were identified. The final recommended set will be presented. Conclusions: Standardized outcome reporting is a necessary component in the movement towards high-value health care. Patient-centered outcomes related to toxicity and disease control can be identified and systemized by a multidisciplinary group of experts. The result of this project is an initial step in what will be an iterative process with the goal of improving the care of all men with prostate cancer. An international pilot project has been proposed based on implementing the final set of recommendations.
